Can not for the life of me...
And the Honda parts manual calls for a D8HS where the "S" stands for "Standard 2.5mm center electrode" and an "A" means "Special Design" so who knows? The center electrode on the D8HS and D6HA may run at about the same temperature even though they have a different heat range number. I attached the NGK numbering guide from their website if you're interested. Again, I'd stick with the D6HA plugs. Save the D8HA's for your Superhawk.

Bear in mind that the 'air screw' is the recessed screw entering the carb body at a downward angle. The 'idle screw' is the knurled screw that protrudes horizontally from the carb.sky1haze wrote:Thank-you Ed and thank-you Steve,
when I first started taking advice about my plugs, someone told me that the screw closer to the engine is the one that I turn 1 1/8 turns, then work with the one on the right..........according to the manual it is the one towards the rear in which I turn 1 1/8 turns and then work with the one to the left....... That could have been my problem the whole time.
Now with the proper adjustment with the screws and the hotter spark plugs, I am ready for a ride with my super low mileage dream. Thanks guys, Really!
Again, Thank-you guys..
48lesco, I am sticking with the D6HA plugs, I noticed they do work bett for my 1966 CA77
Steve, Thanks again for the download. The manual says the complete opposite of what you say. It shows the horizontal screw as the air and the angled as the idle...................I followed the manual and it purrs like a kitten! Double check it for me let me know what you think.. Page 33.

This is very helpful!e3steve wrote:Joel, the air screw only affects the mixture between idle and about a quarter-throttle; but yes, start again from Ed's Magic Recipe and monitor your plugs' colours.
The needle's taper determines the mixture between a quarter and about three quarters gas, and the main jet at WOT, or when the needle is fully retracted.

Well, blow me down! The C handbook is wrong! (lm, davo, teazer, jensen et al will confirm such).sky1haze wrote:Again, Thank-you guys..

I'll correct the misprint myself. It's well known that the wiring diagram in the CB books was wrong also; but now corrected.
